Interactive cultural story-telling virtual environments using San stories
(2004)
Story-telling is being used for the preservation of culture, and interactive story-telling in particular is attractive for its ability to provide the user with a hands-on experience. We explored the feasibility of interactive ...
Visual query tools for uncertain data in space and time
(2004)
The aim of our project was to develop query and visualisation tools for this archive of African art. Our query system had to be designed to cope with different degrees of uncertainty in data, both in time and space. One ...
An object-oriented library for shared-memory parallel simulations
(1996)
Programming shared-memory multiprocessor systems is becoming increasingly difficult as the gap between memory speed and processor speed increases. At the same time, this class of computer-based on standard microprocessors-is ...
Story experience in a virtual San storytelling environment : a cultural heritage application for children and young adults
(2005)
This dissertation explores virtual storytelling for conveying cultural stories effectively. We set out to investigate: (1) the strengths and/or weaknesses of VR as a storytelling medium; (2) the use of a culturally familiar ...
A framework for building spatiotemporal applications in Java
(2001)
A relatively new area of study that first received attention during the past decade explores how spatiotemporal data can be efficiently used in applications and stored in databases. Spatial data includes the locations or ...
A hybrid scavenger grid approach to intranet search
(2009)
According to a 2007 global survey of 178 organisational intranets, 3 out of 5 organisations are not satisfied with their intranet search services. However, as intranet data collections become large, effective full-text ...
Extraction of surface texture data from low quality photographs to aid the construction of virtual reality models of archaeological sites
(2001)
A tool has been designed and implemented to use information extracted from photographs captured using uncalibrated cameras (so-called casual photographs) to fill the occlusions which occur in three-dimensional models of ...
Garbage collection of the PLAVA object store
(2002)
This research investigates the implementation of suitable garbage collection schemes for a persistent store. The store that formed the basis for these experiments was the one developed for a Java Virtual Machine known as ...
Using programming tools in virtual environments
(2002)
Presence is the sense of being in the computer-generated environment. It is regarded as the key to understanding the success of a virtual environment. In this research we focus on desktop virtual environment authoring ...
An extension to optic flow analysis for the generation of computer animated images
(1998)
This dissertation seeks to develop image based animation methods using the technique of optic flow analysis developed for a moving planar object. Image based rendering is presented as a class of algorithm using two dimensional ...
